Multi-shaft energy dissipation self-balancing type self-resetting friction coupling beam damper
The invention discloses a multi-shaft energy dissipation self-balancing type self-resetting friction coupling beam damper which is characterized in that friction energy dissipation can be achieved when the two ends of a coupling beam generate relative shearing displacement and axial displacement, a self-resetting mechanism capable of conveniently controlling the pre-tightening force of SMA alloy wires is introduced, and the self-resetting mechanism comprises an energy dissipation structure and a self-resetting structure; the energy dissipation structure comprises a first energy dissipation structure and a second energy dissipation structure, and the self-reset structure comprises a transverse self-reset structure and a vertical self-reset structure. The coupling beam damper has an energy consumption mode of simultaneously bearing shearing force and axial force under the action of an earthquake, a self-resetting structure provided by the pre-tightening SMA wires provides self-resetting performance for a structural system, the replaceable performance is provided, and meanwhile, the repair time of a building after a disaster is shortened. The coupling beam type damper with the recoverable function has practical significance and engineering application value for development and application of the coupling beam type damper with the recoverable function.
